不好意思又一次用别人的东西………
cocos2d-html5框架无疑是一款优秀、出色的跨平台的开源游戏框架，历经众多产品的考验，核心类cc.Node采用多叉树的结构、cc.Class类可以方便自由的扩充新的对象，一切都是如此美好，使用了一年多时间的cocos2d框架，也做过一些jsb的移植开发，深刻的感受到了coco2d做游戏开发的便利和强大，赞一个！
同时我也在想，前端开发是不是也能方便的用到cocos2d呢？特别是现在的移动web开发，页面的交互逻辑特别多，跟游戏如此相似，所以小狼努力思考、客观实践，终于把coco2d中的核心cc.Class和cc.Node提取出来了（去掉与游戏相关的属性和方法），新添加了cc.Middle(http://www.cnblogs.com/caoke/p/middle.html),也重写了下cc.Director的replaceScene.
工具准备好了，剩下就等着下周1的项目开始了
var layer1=cc.Layer.extend({
context:$("div"),
init:function(){
},
//点击交互事件
initMenu:function(){
},
//开始
onEnter:function(){
this._super()
$("#id").replaceWith(this.context)
},
//结束
onExit:function(){
this._super()
this.context.remove()
}
})
//每个scene对应一个页面
var Scene1=cc.Scene.extend({
onEnter:function(){
this._super()
var layer=new layer1()
layer.init()
this.addChild(layer)
}
})
